There is an image with background and yellow rectangle. The rectangle must drop shadow. I need the shadow to be like in Google Wave. On the attached screenshot you can see that the panel itself doesn't have any border, but it is marked out with shadow from both left and right sides. Please make the shadow as close as possible to one on the Google Wave screenshot.
Final deliverables include:
1) PNG file
2) PSD or [url removed, login to view] (more preferable) file.
